Plutarch

“ Antony was thought disgraced by his marriage with Cleopatra, a queen superior in power and glory to all, except Arsaces, who were kings in her time. Antony was so great as to be thought by others worthy of higher things than his own desires.
As regards the right and justice of their aims at empire, Demetrius need not be blamed for seeking to rule a people that had always had a king to rule them. Antony, who enslaved the Roman people, just liberated from the rule of Caesar, followed a cruel and tyrannical object. ”

“ Demetrius heired a kingdom already won for him by Antigonus, the most powerful of the Successors, who, before Demetrius grew to be a man, traversed with his armies and subdued the greater part of Asia. Antony's father was well enough in other respects, but was no warrior, and could bequeath no great legacy of reputation to his son, who had the boldness, nevertheless, to take upon him the government, to which birth gave him no claim, which had been held by Caesar, and became the inheritor of his great labors. ”

“ Demetrius is alleged by many to have invented false pretexts for his act, and not to have retaliated for injuries, but to have accused one whom he injured himself.
The achievements of Demetrius are all his own work. Antony's noblest and greatest victories were won in his absence by his lieutenants. For their final disasters they have both only to thank themselves; not, however, in an equal degree. Demetrius was deserted, the Macedonians revolted from him: Antony deserted others, and ran away while men were fighting for him at the risk of their lives. ”
